Nearly 80,000 people have signed a virtual card thanking General Mills for its support of gay marriage.

Last month, Minneapolis-based General Mills announced it was opposed to a November referendum asking voters whether the state's law banning gay nuptials should be placed in the Minnesota Constitution.

“For decades, General Mills has worked to create an inclusive culture for our employees. We believe it is important for Minnesota to be viewed as inclusive and welcoming as well. We oppose the proposed constitutional amendment because we do not believe it is in the best interests of our employees or our state economy,” Tom Forsythe, vice president of corporate communications, said in a statement.

Ken Powell, chairman and CEO of General Mills, expressed similar views at a Gay Pride event.

Opponents of marriage equality greeted General Mills' announcement with a four-day protest. The rallies took place across from the company's headquarters and featured demonstrators “dumping” General Mills products into a trailer to be donated to a local food bank.

The Human Rights Campaign (HRC), the nation's largest gay rights advocate, responded with its own action: a virtual card thanking General Mills for its support. As of Wednesday night, nearly 80,000 people have signed the card.
